Problems solved by technology

Thus, it is difficult to disengage the pawls 102h from the receiving portions 103h, and the pawls 102h may disadvantageously be broken due to application of an excessive load when the same are forcibly bent outward to be disengaged from the receiving portions 102h.
Therefore, it is difficult to disassemble the bobbin case 101.
Therefore, the outer size of the ink ribbon cartridge is increased due to the protrusion, and components provided in a printer may disadvantageously come into contact with the protrusion.
